At approximately 4:44 this morning, the Kern County Fire Department responded to reports of a fire on South Mount Vernon at the Greenwaste Facility. The first crew arrived on scene and reported two large wood chip and wood debris piles on fire. The approximate size of the involved piles were 40’ by 40’ and 15’ high. Fire crews made an aggressive attack on the fire using a ladder truck with an elevated hose stream and numerous hand lines to knock the heat out of the fire. Simultaneously, heavy equipment operators from the facility attempted to move not involved piles to a safe distance to prevent the fire from spreading. Strong winds hampered fire fighting efforts and created large flame lengths for fire crews at the scene. The cause of the fire is under investigation. There were no injuries to report.
